2,066,648, dated January 5y 193.7.

In a fire extinguisher of the type indicated, it is desirable to providea container or kit into which a plurality of frangible grenades isplaced on` therein forrendering the grenade crashing means operable toshatter the grenades 'when' subjected to the proper degree of heat. y

A further object is the provision of a container or kit arranged to besupported or suspended for automatic use and provided with a bottomvwall constructed to diffuse and retard the outward ow of the liquidwhen the grenades are crashed.

And a further Objectis the provision of a container or kit havingindividual supports for the grenades positioned in closevproximity witheach other and each of which supports is provided with yheat-controlledgrenade crashing means movable y within the confines of the supportswhen released for operation.

Other objects and advantages will become ap- Figure 5 is a partialdetail perspective view of the bottom wall of rthe kit. d I

The container or kit is designated as i0 and is of skeleton constructioncomprising a back wall l I, porous end Vwalls I2 and I3, respectively,and a 5 porous front wal1I4. A cover I5 is also provided (ci. v1ere- 26)with porous material IS, and is hingedly attached at I'l-I'I to the backWall IIv and provided with alatch i8 to secure the same in closedposition to the front wall lli'. The bottom Wall IS@ ofV the con-4tainer or' kit I Il is crimped transversely lof its e' length and theapexes 2B of ythese crimps-are each provided with a plurality ofrelatively large aligned openings 2I', While the valleys 22 of thecrimps are providedwith a plurality of relatively small yopenings 23.

A plurality of individual L-shaped supports 24 are arranged in closeproximity with each othery in the container'or kit IE.r Thesesupports-are secured to the back wall Il to screws 2525 i arranged inpairs therein and the sup-portsare provided with aligned bayonet slots26e-26 to t L over the screws 25-'25130 hold the `supports in position.The horizontal portion 21m of each of the supports 24 is pro-vided withan annular opening 2'I and a grenade vA containing a're eX- tinguishingliquid' is'positioned in each of these openings of the supports. Thesupports 24 each carry a grenade crashing means designated as a whole as28 and comprises a pair of annular members 29 and 3U, respectively,arranged in super- .posed relation on the horizontal portion 24a of thesupports and pivoted at 3| thereon. Each ari-'- nular member 29 and 3Dis provided with. an eX tending portion 32 and 33, respectively, towhich the free ends of a tension spring 34 are attached, and whichspring serves to pivotally swingthe members 29 and 30 on` their pivot3|. These members 29 and 30 are retained in normal or open position withtheir openings 35 and 36, respectively, aligned with the opening2l inthe horizontal portion 24a ofthe support 24 by means of a heatresponsive element 3'i constructed of a fusible alloy. The grenadesupport 2li` is'v also provided with a resilient U-shaped member 38`secured thereto at 39 and serves to guide the grenade and to yieldinglysupport the `same against movement ywhile positioned in theopening 2l ofthe horizontal portion 24a thereof.

'In the construction of the containerl or kit I0, it will be noted thatthe skeleton frame is arrangedl to form legs 40 which may support 'thesame when placed on a surface and the space between the legs 40 formsopenings at the lower portion of the container or kit to permit the airto circulate under and throughr the bottom wall I9. A handle 4I issecuredto the cover I5 and is of strap-like formation and serves tosupport the container or kit Ill for portab-lepurposes, or as means forsuspending the same.

In its operation, the container or kit I0, when nrv subjected to heat,will permit the heated air to circulate through it by means of theporous end walls l2 and I3, front wall I4 and also through the cover l5and openings 2| and 23 of the bottom Wall i9 around the grenades A. Whenthe heat responsive elements 31 are heated to a degree to melt the same,the tension springs 34 will collapse the annular members 29 and 3U toshatter the grenades A and permit the liquid therein to flow on thebottom wall i9 which will be retarded in its passage through theopenings 2l and 23 and thereby permit the liquid to partially volatilizebefore flowing outwardly of the kit.

I claim:

l. A rire extinguisher of the character described, comprising a kithaving a solid back Wall, porous front and end Walls and a porous coverforming the top Wall, a plurality of grenade supports carried on theback wall, a frangible grenade containing a re extinguishing liquidpositioned on each support, grenade crashing means carried by eachsupport, thermoresponsive means retaining the grenade crashing meansreleasable when subjected to a predetermined degree of heat, and acrimped bottom Wall for the kit provided with small perforations in thevalleys of the crimps and large openings at the apexes of said crimps.

2.1i re extinguisher of the character clescribed, comprising a kithaving a solid back Wall, porous front and end walls and porous coverhingedly carried on the back wall, grenade supports carried on the backWall, a frangible grenade containing a iire extinguishing liquidpositioned on cach support, grenade crashing means carried by each ofsaid supports, thermeresponsive means relcasably retaining the grenadecrashing means releasable when subjected to a predetermined degree ofheat, the bottom Wall o1" the kit being crimped and provided with smallperforations in the valleys of the crimps and large openings at theapexes of said crimps.

3. The combination of claim 2 hereof in which the grenade supports areeach provided with resilient means for releasably retaining the grenadesin the supports.

4. In a fire extinguisher of the character dcscribed, comprising a kitadapted to retain a plurality of hermetically sealed grenades containinga fire extinguishing liquid such as carbon tetrachloride or the like andarranged for manual and automatic disposal of the liquid Within thegrenades, the kit having a solid back wall, porous front and end Wallsand a porous cover forming the top Wall, a plurality of grenadesupports'in the kit, grenade crashing means on each support includingthermoresponsive means retaining the same readily releasable to crashthe grenades when subjected to a predetermined degree of heat, and acrimped bottom wall for the kit provided with small openings in theValleys of the crimps and large openings at the apexes of said crimps.

5. A fire extinguisher of the character described, comprising a kithaving a solid baci: Wall, porous front and end walls and a porouscover, grenade supports carried on the back Wall, a frangible grenadecontaining a rire extinguishing liquid positioned on each support,spring tensioned grenade crashing means carried by each of said supportsincluding thermoresponsive means for holding the grenade crashing meansin tensioned position and for releasing the saine when subjected to apredetermined degree of heat, and a crimped bottom wall for the kitprovided With small perforations in the valleys of the crimps and largeopenings at the apexes of said crimps for retarding and permitting theliquid to partially Volatilize during its flow out- Wardly of the kit.
